VISE.

SPECIFICATION forming part of Letters Patent No. 319,743, dated June 9,1885.

Application filed August 4, 1884. (No model.)

To all whom it may concern: Be it known that I, STEPHEN 0. PARKER,

of Meriden, in the county of New Haven and said drawings constitute partof this specificaa tion, and represent, in-

Figure 1, a sectional side View of the vise; Fig. 2, a top view of thebase or socket, the vise removed; Figs. 3 and 4, modifications.

This invention relates to an improvement in that class of bench -viseswhich are constructed so as to be rotated in a plane with the bench,that the position of the jaws may be changed according to the workrequiredfor the vise.

The object of my invention is the construction of a swivel-vise so thatit may be secured directly to the top of the bench, in substantially theusual manner for attaching Vises which are not swiveled; and theinvention consists in the construction hereinafter described,andparticularly recited in the claims.

A represents the base of the socket, which is constructed with ears orflanges B, by which it may be secured to the bench. It is best recessedupon its under side, as shown. On its upper surface is a circularflange, C, which forms a corresponding circular recess or socket on thetop of the base; D, the base of the stationary part of the vise,constructed upon its under side with a downwardly-projecting trunnion,E, corresponding to the recess within the flange G on the socket, and soas to set therein as in a socket. Through the center of the socket ascrew, F, is introduced into the bottom of the stationary part ofthevise, the head of the screw standing in the recess in the under sideof the base, and so as to take a bearing upon the base and hold the visein the socket, but yet so as to permit its rotation. At some point inthe flange 0 a clamping-screw, G, is introduced in a position radial tothe axis on which the vise turns, and so as to bear against the.trunnion, and so that when the screw is turned hard against thetrunnion E it will clamp the vise in the socket sufficient to hold it toany position to which it may be adjusted. Preferably I apply a shoe, H,between the end of the screw and the periphery of the trunnion E, and insome cases diametrically opposite the clamping-screw I set a block, I,corresponding" to the shoe, so that the trunnion will be clamped betweenthe shoe H and the block I. The bearing-faces of both the shoe and theblock may be roughened or serrated to make a firm bearing against theperiphery of the trunnion. The socket is secured to the bench by screwsthrough the ears B, in the usual manner of securing a non-swivelingvise.

The entire vise is therefore above the plane of the top of the bench andavoids cutting away or defacing the surface of the bench, as isnecessary in vises in which the swiveling device extends into or throughthe bench. By

loosening the screw G the vise may be turned and set to any desiredangle, and there clamped by turning the screw G.

Instead of the screw G as a clamping device, other known equivalents maybe employed-as, for illustration, acam, L, as seen 7 5 in Fig. 3. Itherefore do not wish to be understood as limiting my invention to anyparticular clamping device.

Instead of constructing the socket with a recess and the trunnion on thevise, this order '80 clamping device to secure the vise in the socket atvarious positions, and therefore do not claim, broadly, suchconstruction.

I claim- 1. The combination of the base A, constructed with the circularflange C, forming a 0 circular recess on the top of the base, thestationary part of the vise constructed with a trunnion, E,corresponding to said recess, the screw F, centrally through the baseinto the body of the vise, the clamping-screw G, ar- 5 ranged radiallythrough the flange O, and

shoe Hfietweentheend of the screw and the Iperipher'yofiithe"ti'unnions, substantially as described; 4

2. The combination of the base A, con- 5 structed for attachment to'thetop of the bench,

' and with'tlie circular" flange G upon its upper surface, forming acircular reoess'therein,v the stationary part of the vise constructedwith a trunnion to set intosaid recess, tl m clamping screw; G, shjoe H,and block I, substantially IO as and for the purpose described.
